His name is Cinnamon. He's a male Spice finch, very beautifully feathered. I don't have a picture of him since, frankly, I couldn't pick him out of a crowd if my life depended on it. Besides, I don't know about you, but I'm tired of mediocre photos taken through the cage mesh. Since I haven't yet started opening the Finsterium door to take photos of terrified birds clinging to the walls, we'll just stick with another lovely diagram of his song. We're going to get tired of these things too, I'll bet! But not yet, because this one is really fascinating:

The level lines are pretty whisles, and the others are trills. I know what you're thinking: "Didn't she say that
Ovaltine's song is a trill?" Well, you're right. I've described Ovaltine's song as a
riotous trill (before I'd actually named him), and as a
loud crow. I stand by both these descriptions, since a trill is a trill, and crowing fits any loud bird's song heard before the sun actually comes up. So look, here's Ovaltine's song:

Imagine my surprise when I discovered I had
two loudly crowing, rioutously trilling birds! It explains why I don't have a problem waking up in the morning.
Now, I've simplified these diagrams, partly because the birds rarely cooperate with me when they know I'm watching, and partly because I'm pretty sure that all the new Finsters sing each other's songs, rearrange their feathers, and put on each other's leg bands when I'm not looking, just to mess with my head. But trust me when I say that although Cinnamon and Ovaltine's songs aren't exactly alike, their trills are — particularly that rising one at the end. Ovaltine often sings just the last two trills of his song in the morning, sometimes adding an extra rising trill at the end. Cinnamon is also fond of that single, rising trill. Ovaltine is louder. No wait, let me rephrase that: OVALTINE IS LOUDER.
These birds must have grown up together, or gone to the same finishing school, or something. And while I wouldn't use the ovaltine beverage for this (a nice, dark chocolate with at least 70% cacao content is best), cinnamon and hot chocolate make a very nice pairing!
